Yeah, ok. Sure, there was zero snow in Marquette in 1965, and very little in all of the 1960s [even though that was a very cold and snowy decade - as you know, more than most!]. As Joe Biden would say, c'mon man! Those early snow totals in Marquette [which lead to the extreme positive trend] aren't even remotely believable.
And it's completely irrelevant. Your winter climate is much more similar to that of Toledo or even Columbus, than Marquette. Get real.
